Inlet Thermistor Removal
1. Remove the rear panel to access the
thermistor.
2. Disconnect the thermistor harness connector.
3. Remove one 1/4-inch hex-head screw
securing the thermistor to the supply duct and
pull out from the supply duct.
The inlet thermostat is located on the side of
the electric heater on electric model dryers.
The thermostat opens at 255°F and closes at
232°F. On gas dryers, it is located on top of the
combustion chamber. The thermostat opens at
221°F and closes at 200°F.
Backup
Thermostat Diagnosing
Continuity can be checked at the thermostat or
from the main board. From the main board on the
electric dryer, check from the common terminals
of K502 or K501 relays to the line one side of the
power cord or terminal block.
NOTE
: Disconnect
the J101 connector from the main board to
prevent a false reading. If there's no continuity
found, either the inlet or outlet backup thermostat
could be open as they are in the same circuit.
On gas dryers, continuity can be checked at
the thermostat or from the normally open (N.O.)
terminal on the K501 relay to gas valve. If there's
no continuity found, either the inlet or outlet
backup thermostat could be open as they are in
the same circuit.
